Frequently Asked Questions | FAQs
What is a 16mm SDS Max drill bit used for?
SDS Max drill bits feature a thicker, more robust shank than standard SDS Plus bits, allowing them to handle the extreme power of heavy-duty rotary hammers. A 16mm SDS Max bit is ideal for drilling deep holes into tough concrete, reinforced masonry, and blockwork for large structural anchors and heavy fixings.
What is the best 16mm drill bit for drilling into timber joists?
For routing cables and small pipes through timber joists, a 16mm flat wood bit (spade bit) or a tri-flute wood drill bit is the best choice. These bits are engineered for rapid cutting and fast waste removal, leaving a clean 16mm clearance hole with minimal effort and splintering.
How can I fit a 16mm metal drill bit into a standard drill chuck?
Most standard power drill chucks have a maximum capacity of 10mm or 13mm. To drill a 16mm hole in metal without upgrading your power tool, you should look for a 16mm reduced-shank HSS drill bit (sometimes called a blacksmith drill bit). These feature a stepped-down base that fits perfectly into standard chucks.
